We are aware of this and this is being tracked in https://bugzilla.redhat.com/show_bug.cgi?id=1933772 *** This bug has been marked as a duplicate of bug 1933772 *** The duplicate of bug 1933772 was verified, but we still hit this problem when upgrade from 4.7 to 4.8 nightly, so I have to reopen the bug.

From what you pointed out the error is listed as Unable to apply 4.8.0-0.nightly-2021-04-25-110331: timed out waiting for the condition during waitForDaemonsetRollout: Daemonset machine-config-daemon is not ready. status: (desired: 5, updated: 5, ready: 3, unavailable: 2) Which at a glance looks like the same issue, but if you look at the nodes, there is 1 master and 1 worker that has NotReady,SchedulingDisabled, which means they never came back up after reboot. The daemon logs for those nodes are also empty, indicating that this is not the same issue (instead of the pod itself crashlooping, it actually isn't running at all) So it seems that the 2 nodes didn't update properly, so they could be stuck in a booting phase, or have failed services (e.g. kubelet) such that they are unable to rejoin the cluster. Are you able to access either the console or ssh into either of those nodes to see what may be going on? If we find something else as the cause we should perhaps open another BZ. jerzhang, you are right, I dug deeply, fuond the root reason is the following error, namespaces/openshift-monitoring/pods/cluster-monitoring-operator-8767f9b5d-xfdcg/cluster-monitoring-operator/cluster-monitoring-operator/logs/current.log:85:2021-04-25T20:05:19.044608892Z E0425 20:05:19.044589 1 operator.go:400] sync "openshift-monitoring/cluster-monitoring-config" failed: running task Updating node-exporter failed: reconciling node-exporter DaemonSet failed: updating DaemonSet object failed: waiting for DaemonSetRollout of openshift-monitoring/node-exporter: got 2 unavailable nodes I reopened the bug 1937888, will close this bug. |
Description of problem: The machine-config-daemon pods are crashing without recovery which is leading to the machine-config cluster operator being in a degraded state and thus blocking the upgrades. - lastTransitionTime: "2021-04-07T01:15:24Z" message: 'Unable to apply 4.8.0-0.nightly-2021-04-05-174735: timed out waiting for the condition during waitForDaemonsetRollout: Daemonset machine-config-daemon is not ready. status: (desired: 257, updated: 257, ready: 247, unavailable: 10)' reason: MachineConfigDaemonFailed status: "True" type: Degraded Looking at the failed machine-config-daemon pods, they are unable to find the nodes which are part of the cluster: W0407 02:35:53.118424 573073 daemon.go:635] Got an error from auxiliary tools: error: cannot apply annotation for SSH access due to: unable to update node "nil": node "ip-10-0-181-219.us-west-2.compute.internal" not found I0407 02:35:53.118448 573073 daemon.go:636] Shutting down MachineConfigDaemon F0407 02:35:53.118485 573073 helpers.go:147] error: cannot apply annotation for SSH access due to: unable to update node "nil": node "ip-10-0-181-219.us-west-2.compute.internal" not found Logs including the cluster-operators, openshift-machine-config-operator and failed pods can be found here: http://dell-r510-01.perf.lab.eng.rdu2.redhat.com/large-scale/4.8-sdn/upgrades/. Version-Release number of selected component (if applicable): OCP 4.7.5 -> 4.8.0-0.nightly-2021-04-05-174735 upgrade How reproducible: Always Steps to Reproduce: 1. Install an OpenShift cluster using 4.7.5 payload. 2. Upgrade to 4.8.0-0.nightly-2021-04-05-174735 nightly build. 3. Observe the machine-config cluster-operator status and machine-config-daemon pods during the upgrade run. Actual results: Upgrade gets stuck while rolling out the machine-config-daemon daemonset with a couple of pods crashing. Expected results: Successful Machine-config cluster operator rollout during the upgrade runs.
